SLUB-CATGHEB.

Specification of Letters Patent.

Patented June 30, 1914.

Application filed April 1, 1913. Serial No. 758,165.

Be it known that I, Moses EWING, a citizen of the United States, residing at Chester, in the county ofDelware and State of Pennsylvania, have invented certain new and useful Improvements in Slub Catchers, of which the followin is a specification.

My invention refittes to improvements in slub'catchers, and more particularl to an improved slub catching attachment or cone winders, the object of the invention being to provide an efiicient slub catcher which will clear the thread, preventing lumps or slubs from passing to the cone and causing the threadto break bGfOTQ'PGIHIIttIIIg a slub or lump to pass.

A further object is to provide a slub catcher comprising two brushes supported at the ends of lazy tongs which are supported in such a manner that when the thread breaks, the brushes will separate and the cone beelevated out of contact with its friction' drivingroll.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as willbe more fully hereinafter described and pointed out in the claims.

In the accompanying drawings. Figure 1 is a view party in section and partly in side elevation illustrating my improvements in' normal operative position. Fig. 2 is a plan view of theslu catcher per as. Fig. 3 is a view similar to Fig. lshowing the position of the parts when the thread breaks. Fig. 4 is a perspective view of one of the brushes. Fig. 5 is a view in cross section on the line 5-4) of Fig. 2. Fig. 6 is a view in front elevation with the parts as shown in Fig. 1, and Fig. 7 is a perspective view of the wire frame supporting bracket.

My improvements are used in connection with a cone Winding machine, and I have illustrated in connection with my, improvements, only such portions of the machine as are necessary to illustrate the carrying out of my invention.

1 is a horizontal bar constituting a fixed or stationary part of the machine frame having brackets 2 secured thereon and supporting a shaft 3 containing a roll 4 which is adapted to frictionally turn a cone 5 when the latter rests thereon. This cone 5 is supported by a rotary holder 6 secured to one member 7 .of a bell-crank-lever 8 which is pivotally supported on a rod9 mounted in extensions 10 on brackets 2.

The brackets 2 are made with bearings 11 to receive arbors 12 secured in sleeves 13 on a plate 14, and aiford pivotal mounting for this plate. Plate Ifi: is made with posts 15 at its upper end in which a wire guide 16 is secured and over this guide 16, the thread.

to be wound on the cone is passed, and is directed onto the cone by a guide 17 mounted to slide on a bar 18 and operated by a cam 19, a fragment of the latter being illustrated.

' On the lower end of plate 14, a relatively long arm 20 and a relatively short arm 21 are cast integral with the plate and support a rod 22. A catch 23 is pivotally supported between its ends on the rod 22, and is normally held in an elevated position by a wire frame 24 which is supported in a bracket 25 secured to the plate 14. This wire frame 24 at one end has a crank arm 26 which bears against the shorter end 27 of'catch 23, while the opposite end of this wire frame consti tutes a horizontal guide 28 under which the cord 17 is positioned and maintained elevoted by the cord.

As soon'as the cord breaks, the frame 28 will fall and permit the catch 23 to fall to the position shown in dotted lines in Fig. 1 into the path of movement of an oscillating trip 29, continuously oscillating with a shaft 30. When the catch falls to this position, the downward oscillating movement of the part 29 will turn the plate downwardly upon its arbors 12 to the position shown in Fig.

The plate is held in its normal operative position by a spring 31 secured on bar 1, and having a curved recess 32 in its free end, which receives a rotary sleeve 33 on a pin 34 fixed in integral cars 35 on the bottom of plate 14. When the plate is pulled downwardly by the oscillator 29, the sleeve will be drawn rearwardly out of the recess 32, and lie in the position shown in Fig. 3. When again elevated, the recessed end 32 will spring upwardly and hold the 'parts in normal position as will be readily understood.

A frame 36 is pivotally mounted on the rod 22, and is formed at one end with a finger hold 37. This frame when moved up wardly by the finger hold 37 will engage the shorter end of catch 23, hold the same in elevated position, and allow the plate 1-1 to be raised to operative position without stop ping the oscillator 29. In other words, this upward movement of the plate. by means of the frame 36, first'swings the catch 23 out of the path of the oscillator 29, and when the plate is elevated and the cord in operative. position with relation to the wire frame 24, the catchwill be held in this position.

39 in a bracket 40 on one of the posts 15. The teeth of this bar 38 engage the lower wall of the slot 89, so that when the platelt falls, bar 38 will be drawn forwardly and elevate the cone 5 out of engagement with roll 4:, thereby stopping the turning of the mud The teeth of bar 38 are inclined or ratchet shaped, so that as the cone increases in diameter, this bar may be moved rearwardly tooth by tooth so that the cone Wlll be elevated regardless of its diameter in the event the thread breaks.

I The relatively long, arm 20 supports at its free end a short rod 41 on which a table at); is secured. This table $2 at its outer edge has a guide as through whichthe cord 17 is drawn, and on the a table a rotary weight as is mounted on a vertical post 45' and bears upon the cord to act as a tension device. frame 24:, th cord passes through 111 1m-' proved slub catcher, which consists 0' two brushes 46 facing each other and supported in holders 47 fixed to the ends of a lazy tongs 4E8. Thislazy tongs 4.8' comprises four links as clearly shown in Fig. 2 piv v otally connected as shown, and one pivotal connection at the lower end ofthe lazy ton 5 consists of a bent rod 49 which is rigid y secured to the frame bar 1, and acts as'a stationary pivot for the lazy tongs. The

upper pivot 48* of the lazy tongs comprises a screw which is secured to arm 25 o bracket 25, so that when the plate ltmoves downwardly, the lazy tongs operates. to"

separate the brushes as clearly shown.

The brushes each consist of a backing plate 50 preferably of fabric through which a large number of wires 51 project, forming an extended wire surface. The backing plates 50 are adapted to he slid into and out of the holders 47, so that the brushes maybe readily replaced when worn or broken.

When the plate 14: is elevated to operative position, the lazy tongs 48 will bring the. brushes together, engaging the thread 17 with the teeth of the brushes located side 4 by side, that is, the teethv of one brush will .and when the parts are moved back to norapparatus.

.l aim as new and desire to secure by Let- 5 ters Patent is:
